Yes, if people frequently wear the eyelash extensions for too long a time, their own eyelashes will certainly get damaged to some extent. This is because that wearing eyelash extensions for a long time every day can reduce the cleanliness of the real eyelashe, Each of the real eyelash is rooted in the hair follicle which is the passageway for the skin to discharge the foreign matters. Besides, there are many sweat glands and sebaceous glands at the root of the eyelashes. Therefore, if people usually wear eyelash extensions for a long time, their sweat pores will easily be blocked off by the eyelash extensions, thus hindering the sweat pores from normal perspiration. Then there will be some eye problems coming along, such as conjunctivitis, eyelid swelling, eyelashes falling off in a large amount, and so on. Therefore, people had better not wear eyelash extensions every day. Instead, allow the eyes to have rest by only wearing them three to four times a week. In addition, when wearing the eyelash extensions, people should use professional quality eyelash glue. And the eyelash extensions should be put on and taken off in the right way. Then the harm and side effects of eyelash extensions can be reduced to the least.
